How do I get a list of active ports and applications using them in a Windows Server 2003 box?
Any free utilities?
TCPView is pretty handy.
netstat -o is already on the system.
nmap -v hostname
Nmap is the most thorough port scanner ever made.
What about SysInternals (now Microsoft) tools like Process Explorer or TCPView?
Another useful utility is fport. It's a bit like netstat -o, but it shows the process name and application path in addition to the PID.
